Fire Barrier Moldable Putty Pads MPP+ are typically used as a wall opening
protective to meet building requirements, for protection of membrane penetrations made by listed steel or non-metallic electrical boxes. It is also used to seal gaps
between cables in multiple penetrations (including fiber optic inner duct) and to firestop cable bundles, insulated pipe, electrical conduit and metal pipe. Larger
sized pads, 7 in. x 7 in. and 9.5 in x 9.5 in. (177.8mm x 177.8mm and 241.2mm x 241.2mm) are widely used to firestop metallic and non-metallic electrical outlet
boxes up to 14 in. x 4.5 in. by 2-1/2 in. (355.6mm x 114.3mm x 63.5mm) deep. For larger applications, pads can be molded together by hand.

Consult a 3M Authorized Fire Protection Products Distributor / Dealer or Sales Representative for
Applicable UL, Intertek or other third-party drawings and system details.
6. Installation Techniques
Preparatory Work:
Installation Details:
The surface of the electrical box, or opening and any penetrating items should be cleaned (i.e. free of dust, grease, oil, loose materials, rust or
other substances) to allow for the proper adhesion of the 3M
™
Fire Barrier Moldable Putty+ Pad. Ensure that the surface of the substrates are not
wet and are frost-free.
Electrical boxes must be firestopped under the following conditions: boxes larger than 16 sq. in. (103 sq. cm), if horizontal spacing between
boxes is less than 24 in. (609.6mm), when multiple boxes are located in one stud cavity or if the aggregate of all boxes exceeds 100 sq. in.
per 100 sq. ft. (645 sq. cm. per 9.29 sq. m) — refer to listed system details and applicable local building code requirements. For electrical box
installations, a minimum of 1/10 in. (2.5mm) thick putty application is required. 3M
™
Fire Barrier Moldable Putty Pads MPP+ are to be installed
to completely cover the exterior of the outlet box (except for the side against the stud). To firestop penetrations, install the applicable depth of
backing material (if required), remove the desired amount of putty from the pad, form (if necessary) and install as detailed within the listed
system. Make sure that putty is in complete contact with the substrate and penetrating item(s).
Note: Partial pads can be pieced together and the seams between partial pads should overlap a minimum of 1/8 in. with the seams
worked with the fingertips to create adhesion at the seam.
Limitations:
Over application (i.e., using excessive amount of material) of product to vertical surfaces may cause sagging, follow system details. Product is
not impaired by freezing but should be warmed to 32°F (0°C) before applying.
No maintenance is expected when installed in accordance with the applicable UL, Intertek, FM or other third-party listed system.
Once installed, if any section of the 3M
™
Fire Barrier Moldable Putty Pad MPP+ is damaged, the following procedure will apply: remove damaged putty, clean the
affected area and install the proper thickness of putty, ensuring it bonds to the substrate and adjacent putty (product from damaged area can be reused if it is free from
contaminants). Putty can be molded together at new/existing putty overlap.
